摘要:
A system and method for adaptive and predictive analysis of sensor readings to track documents in a document processing system. The system comprises: a plurality of sensors for sensing a document, wherein each sensor includes an associated filtering system for filtering sensor readings, and a performance tracking system for collecting performance data; and a control system that and adjusts filtering characteristics of the filtering system based on the collected performance data. In addition, a correlation system is provided for using data from at least one upstream sensor to interpret an ambiguous downstream sensor signal.

A paper thickness measuring device for use in a rotary paper feeding device having a rotating cylindrical drum. In a preferred embodiment of the present invention, a gripper is mounted on the cylindrical drum for gripping a sheet; and a target is mounted on the cylindrical drum and mechanically linked to the gripper such that a position of the target corresponds to displacement of the gripper by a gripped sheet. The target is arranged and configured for detection of the target position a predetermined time or at a downstream location after the gripper grips a sheet.

A paper press member 240 configured to be capable of advancing and retracting with respect to a paper guide 220 is provided between a paper feed roller 234 and the front end in the paper feed direction of paper loaded in a manual feed tray 230. When a plurality of sheets of paper enter into the press-contact section between the paper feed roller 234 and a reverse roller 235, the reverse roller 235 is rotated in the reverse direction to retract the sheet on the reverse roller side to the manual feed tray 230. At this time, by causing the paper press member 240 to project from the upper surface of the paper guide 220, the sheet to be retracted and the paper press member 240 come into contact with each other, so that the travel amount of the sheet when retracting the sheet is reduced.

A sheet feeding device includes a driven roller that rotates in response to movement of a sheet, and a rotary encoder that detects a moving distance of the sheet based on rotation of the driven roller. The driven roller and the rotary encoder are connected by a gear unit having backlash. When the sheet moves in a reverse direction and thereby the driven roller rotates in reverse, the rotary encoder does not detect the moving distance of the sheet.

A delivery system comprises a frame, and a plurality of hoppers attachable to the frame in a vertically spaced apart arrangement. The hoppers are each configured to hold a plurality of sheet-like materials. At least one upper belt is movably coupled to the frame, with the belt being configured to move the sheet-like materials downward from the hoppers. At least one contact roller is disposed below each hopper, and at least one suction apparatus that is associated with each hopper. A moving system is configured to move the suction apparatus toward and away from the hopper to grasp and remove one of the sheet-like materials from the hopper, and to move the removed sheet-like material downward until grabbed by the contact roller.

An individual sheet member output control method used in a sheet member dispenser to control reversing of a transferring roller set for a secondary dispensing by a dispensing roller set when a sensor detected delivery of overlapped sheet members toward a sheet member outlet. The reversing and re-dispensing procedure is repeated to have overlapped sheet members be separated, and the transferring roller set is reversed to move overlapped sheet members backwards and then the machine is shut down for examination if overlapped sheet members still cannot be separated after the reversing and re-dispensing procedure has been repeated a predetermined number of times.

A sheet feeding device includes a stacker on which sheets are placed, a sheet feeding device for separating and feeding a sheet from other sheets on the stacker, a sheet overlap sensing device placed in a sheet conveying path at a downstream side of the sheet feeding device, and a sheet sensing device for detecting whether the sheet is located in the sheet overlap sensing device. An error determining device determines whether the sheet overlap sensing device is operating normally.

The invention provides a double feed sensing device capable of sensing double feed of paper sent out for the first time. The double feed sensing device includes a thickness sensing unit for sensing thickness of cut paper conveyed, a rigidity sensing unit for sensing bending rigidity of the conveyed paper, and a double feed determining unit for comparing a value of the thickness of the paper sensed by the thickness sensing unit and a value of the bending rigidity of the paper sensed by the rigidity sensing unit with threshold values of thickness and rigidity of the paper set based on values of thickness and bending rigidity of one sheet of the paper and values of thickness and bending rigidity of stacked sheets of the paper, so as to determine whether the paper is double-fed or not.
摘要:
A multifeed detection apparatus and method for use in a check processing terminal including a paper supply unit for individually feeding a plurality of checks from the paper supply unit along a check transportation path in a given direction; a MICR head having a non-movable contact surface on one side of the check transportation path; a pressure member disposed on another side of the check transportation path opposite the non-movable contact surface for pressing one or more transported checks between the pressure member and the MICR head; and a displacement detection sensor for detecting physical displacement of the pressure member from the non-movable contact surface to indicate check thickness.
